Definitions
- This invention relates to a process for the direct sulfation of mixtures of primary alcohol polyethers and secondary alcohols or secondary alcohol polyethers with chlorosulfonic acid. It also relates to a method of producing mixtures of primary alcohol polyethers and secondary alcohol polyethers and the product.
- Another object of the present invention is the development of a process of direct sulfation which comprises the steps of reacting a mixture of (1) from about 0.15 to about 0.9 mol equivalents of an alcohol selected from the group consisting of a polyethyleneglycol alkyl ether of the formula wherein R represents a member selected from the group consisting of alkyl having from 5 to 19 carbon atoms, alkenyl having from 5 to 19 carbon atoms, and hydroxyalkyl having from 5 to 19 carbon atoms and n represents an interger of from 2 to 17 and a polyethyleneglycol alkylaryl ether of the formula bon atoms and the total of the carbon atoms in R and R is from 5 to 19', and secondary alcohol ethoxylates of the formula wherein R and R are alkyl havingfrom 1 to 18 carbon atoms and the total of the carbon atoms in R and R is from 5 to 19, and yis an integer of from 0 to 20, with from about 0.9 to about 1.25 mol equivalents per hydroxy
- a further object of the invention is the development of a process for the production of a mixture of sulfated alcohols having a sulfation degree of at least 80% which consists of the steps of reacting from about 0.9 to about 1.25 mol equivalents per hydroxyl group of anhydrous chlorosulfonic acid with a mixture of (1) from about 0.15 to about 0.9 mol equivalents of a polyethylene glycol alkyl ether of the formula wherein x represents an integer of from 4 to 18 and n represents an integer of from 2 to 17 and (2) from about 0.1 to 0.85 mol equivalents of a secondary alcohol ethoxylate of the formula CHa-(CHg)...0H(GH.).-CH.
- n O(CH CH2O)nH wherein m is an integer of from O to 17, 0 is an integer of from 0 to 17 and the sum of m -l-o is an integer of from 3 to 17, and n is an integer of from 2 to 17, at a temperature of from about 0 C.
- a yet further object of the invention is the development of a process for the production of a mixture of primary alcohol polyethers and secondary alcohol polyethers containing unreacted alcohols which comprises the steps of reacting one mol of a mixture of (1) from about 0.15 to about 0.9 mol equivalents of a primary alcohol of the formula wherein R represents a member selected from the group consisting of alkyl having from to 19 carbon atoms, alkenyl having from 5 to 19 carbon atoms, and hydroxyalkyl having from 5 to 19 carbon atoms, and (2) from about 0.1 to 0.85 mol equivalents of a secondary alkanol of the formula Ii -C Ill-R:
- R and R are alkyl having from 1 to 18 carbon atoms and the total of the carbon atoms in R and R is from 5 to 19, with from 2 to 17 mols of ethylene oxide in the presence of an acidic catalyst at a temperature below ambient temperature, and recovering a mixture of primary alcohol polyethers and secondary alcohol polyethers containing unreacted alcohols.
- secondary alcohols and secondary alcohol ethoxylates may be sulfated directly utilizing chlorosulfonic acid when the reaction is conducted in the presence of a primary alcohol ethoxylate or an alkylaryl ethoxylate.
- No solvent is required in the reaction, although a solvent can be employed if desired.
- the product of the reaction after neutralization is a mixture of sulfates of the primary alcohol ethoxylates and the secondary alcohol or secondary alcohol ethoxylates. Both of the sulfatescontribute to the surface activity of the mixture and the mixture is useful primarily as a detergent.
- the presence of the straight chain secondary alcohol ethoxylate sulfate does not impair the biodegradability of the product and greatly decreases the time required for the mixture to become degraded through biological activity.
- the presenceof the primary alcohol ethoxylate in the sulfation mixture is critical for the progress of the sulfation reaction.
- a range of from about to 90 mol percent or higher of primary alcohol ethoxylate may be employed.
- the ratio of primary alcohol ethoxylate to secondary alcohol and/or secondary alcohol ethoxylate may be varied depending on the type of final mixture of sulfated alcohols desired within the above range.
- the primary alcohol ethoxylate is preferably a polyethyleneglycol alkyl ether of the formula wherein R represents a member selected from the group consisting of alkyl having from 5 to 19 carbon atoms, alkenyl having from 5 to 19 carbon atoms, and hydroxyalkyl having from 5 to 19 carbon atoms, and n represents an integer of from 2 to 14. It is advantageous to have the recurrent CH2CH2-O units represent from about 15 to 90% of the total weight of the primary alcohol ethoxylate molecule or for n to have an average value of from about 3 to about 10.
- primary alcohol ethoxylates which contain mixtures of higher alkanols of varying chain lengths which can be from natural sources such as the fatty alcohols or from synthetic sources as obtained from petroleum.
- the primary alcohol ethoxylates may be straight chain or branched chain.
- alkylphenol ethoxylates or alkylnaphthol ethoxylates may be employed.
- the various primary alcohol ethoxylates which are utilizable in the process are the primary higher alkanol ethoxylates such as the commercial products Alfonic 1014-4 (a mixture of C to C alcohols derived from petroleum containing 40% polyoxyethylene content or an average of 3 polyoxyethylene units); Alfonic 810-6 (a mixture of C to C synthetic aliphatic alcohols containing 60% polyoxyethylene content or an average of 5.5 polyoxyethylene units); Alfonic 1012-6 (a mixture of C to C synthetic aliphatic alcohols con taining 60% polyoxyethylene content or an average of 5.25 polyoxyethylene units); a laurryl alcohol ethoxylated with about 3 polyoxyethylene units; polyethylene glycol alkenyl ethers, such as oleylpolyoxyethyl alcohol having about 5 polyoxyethylene units; and polyoxyethyleneglycol hydroxyalkyl ethers, such as l2-hydroxy-octadecylpolyoxyethyl alcohol having about 6 polyoxyethylene units
- alkylphenol ethoxylates and alkylnaphthol ethoxylates are alkylphenol ethoxylate having an average of 4 polyoxyethylene units and an average of 9 carbon atoms in the alkyl portion of the molecule.
- the secondary alcohols are those having the formula wherein R and R are alkyl having from 1 to 18 carbon atoms and the total of the carbon atoms in R and R is from 5 to 19, and preferably those having the formula g the above secondary alcohols such as a straight chain secondary alcohol ethoxylate having from 11 to 15 carbon atoms in the alcohol moiety with an average of 4 polyoxyethylene units, and Tergitol 15454, a straight chain secondary alcohol ethoxylate having from 11 to 15 carbon atoms in the alcohol moiety with an average of 3 polyoxyethylene units.
- ethoxyla-ted mixtures of primary and secondary alcohols may also be employed advantageously.
- These ethoxylated mixtures can be utilized as prepared without separation of the ethoxylation by-products (polyglycols and unreacted alcohols) as the by-produc-ts also undergo sulfation and are valuable components in the final product.
- These ethoxylated mixtures have a considerable advantage over the use of physical mixtures of primary alcohol ethoxylates with secondary alcohols and/ or secondary alcohol ethoxylates in the sulfation reaction since they are inherently less expensive to produce.
- the sulfation reaction is conducted by gradually adding chlorosulfonic acid to the mixture of alcohols while agitating and cooling to maintain the temperature between about 0 C. and C. From about 0.9 to about 1.25 mols of chlorosulfonic acid are employed per mol equivalent of hydroxyl groups present in the mixed alcohols.
- the reaction is preferably conducted while passing air or other inert gas therethrough in order to remove the HCl formed by the reaction.
- the reaction is advantageously carried out by continuous methods, introducing metered amounts of the alcohol mixture and the chlorosulfonic acid into a cooled reactor.
- the reaction must be conducted over a period of time of from 5 to 60 minutes, depending on the rate of addition of the chlorosulfonic acid and the rate of cooling of the reaction mass.
- the temperature of the reaction is preferably maintained below 50 C. As the temperature of the reaction increases substantially above about 35 C., some by-prodnets are formed decreasing the degree of sulfation of the mixed alcohols.
